Product Features
Technical Overview
This direct attach cable implements the 40GBASE-CR4 Ethernet standard, delivering aggregated 40 Gbit/s throughput through four 10 Gbit/s lanes. The QSFP+ connector on one end breaks out to four individual SFP+ connectors on the opposite end, enabling flexible connectivity between 40GbE and 10GbE interfaces.
The passive twinaxial construction provides inherent electrical advantages for short-reach applications, including lower power consumption and reduced heat generation compared to active optical alternatives. This design choice makes the cable particularly suitable for high-density deployments where thermal management and energy efficiency are priorities.
Key Product Advantages
This DAC cable offers several practical benefits for network administrators seeking reliable, high-performance interconnects without the complexity of fiber optic solutions. The combination of QSFP+ to SFP+ breakout capability with passive twinaxial construction creates a versatile connectivity tool for modern network infrastructure.
Simplified Connectivity
The 1:4 breakout configuration allows a single 40GbE port to connect to four 10GbE devices, reducing port requirements and simplifying cable management in dense network environments.
- Eliminates multiple individual cables
- Reduces clutter in cable trays
- Simplifies port planning and allocation
Cost-Effective Performance
Passive twinaxial construction provides reliable 40 Gbit/s connectivity at a lower total cost of ownership compared to active optical cables or transceiver-based solutions.
- No external power required
- Lower initial investment
- Reduced ongoing operational costs
Deployment / Use Cases
This cable is specifically designed for Alcatel network devices, making it ideal for organizations standardizing on Alcatel networking equipment. The 3-meter length provides sufficient reach for typical rack-to-rack or within-rack connections in data center environments.
Primary deployment scenarios include connecting 40GbE switch uplinks to 10GbE server interfaces, aggregating multiple 10GbE connections into a single 40GbE port, and creating high-speed interconnects between network devices in enterprise data centers. The cable's passive design ensures compatibility with standard QSFP+ and SFP+ ports without requiring special configuration or management.
Data Center Interconnects
Connect top-of-rack switches with 40GbE uplinks to servers with 10GbE interfaces, optimizing bandwidth utilization while maintaining backward compatibility with existing 10GbE infrastructure.
Network Aggregation
Consolidate multiple 10GbE connections into a single 40GbE port on core switches or routers, reducing port count requirements and simplifying network architecture.

FAQ
What type of cable is the Axiom QSFP4X10GC3M-AX?
This is a direct attach copper (DAC) cable with twinaxial construction. It uses passive electrical signaling rather than optical technology, making it suitable for short-distance connections up to 3 meters (9.8 feet) with lower cost and power consumption compared to active optical alternatives.
What devices is this cable compatible with?
The cable is designed for Alcatel network devices and supports standard QSFP+ and SFP+ interfaces. It implements the 40GBASE-CR4 Ethernet standard, ensuring compatibility with equipment that supports this specification. The passive design works with any compliant QSFP+ port and SFP+ ports without requiring special drivers or configuration.
What is the data transfer rate of this DAC cable?
This cable provides 40 Gbit/s total throughput using the 40GBASE-CR4 standard. The QSFP+ end aggregates four 10 Gbit/s lanes that break out to individual SFP+ connections, allowing simultaneous 10 Gbit/s data transfer on each of the four SFP+ ports while maintaining full 40 Gbit/s capacity on the QSFP+ interface.
How does the passive design benefit network deployment?
The passive twinaxial construction requires no external power, reducing complexity and potential points of failure. This design eliminates the need for signal conditioning electronics within the cable, resulting in lower latency, reduced heat generation, and simplified deployment since there are no active components to configure or manage.
